Vladamir Putin should send 150,000 Russian troops on the ground to Syria to combat Isis because bombing Isis will not be effective in defeating them. Airstrikes will not work in defeating isis because the savages(isis) will keep coming back to the same areas over and over again and trying to take control of it. One of the most efficient ways to stop your enemy from advancing is to defeat him face to face. And Russia has had experience with this kind of enemy. Russia has had experiences for 15 years in fighting islamic militants in the first and second Chechen war. The first Chechen war which was a defeat for the Russian army was from 1994 to 1996. Which resulted in the deaths of 5732 Russian troops and 3000 Chechen militants. In the second Chechen war which lasted from 1999 to 2009 resulted in the deaths of 16299 Chechen militants and 7217 Russian soldiers. So Russia has experienced this kind of warfare for 15 years. And no military in the 21st century has sent troops in the 100,000's range to fight an insurgency. For example,During the start of the war in Afghanistan after 9/11 the us sent sent 1300 american troops to Afghanistan. Russia sending 150,000 troops to Syria in order to fight isis is considered an overkill. Especially went it comes to fighting dirty scumbag savage isis in Syria. I want to say one last thing, i as an Iraqi sunni muslim will stand with the Russian president vladamir Putin in this fight against this cancerous radical-wahhabism that is spreading throughout the world.

In my opinion, (as I'm the con) I believe using on-foot soldiers to fight Islamic State isn't the best idea.

Islamic State, blatantly, are extremely powerful. With access to media and bases covering both Iraq and Syria, it would put up much more of a fight than previous wars with existing nations. With countries like the United States already attempting to intervene with ground troops in Somalia and Lebanon, it hasn't turned out well and eventually they take a blow from the impact and loss of ground. This may well happen to Russia if they end up deploying troops.

It would also give the Islamic State easy targets to kill troops. As they are widely populated and spread out across the region, no doubt would there be a far more superior amount of ISIS militants to Russian troops, meaning they would overpower them. It would also make them (ground troops) vulnerable for captivity and eventually used as pawns in order to receive want IS want.

As there are already Kurdish forces and many other local militants fighting IS, there really is no point sending in vulnerable troops that are likely to be ambushed or taken a big impact on the army itself. The United Kingdom and France are already anticipating in Air-Strikes against the terrorist groups and sending in troops will only make matters worse.
